docs(reviewer): add external audits — test/error-handling, API/perf, CGAL readiness
Three complementary, self-contained audit documents (each actionable by a
fresh session, with file:line, code snippets, fixes, acceptance criteria):
- test-coverage-error-handling-audit: coverage gaps + error-handling robustness;
agreed gate 80% line / 70% branch / 90% function.
- api-performance-audit: API-naming consistency (A1–A5, decided) + Newton-solver
performance (B1 block-FD, redundant gradient evals, factorization reuse).
- cgal-submission-readiness-audit: G0 porting-rights blocker (original is
unlicensed Varylab/TU-Berlin code; this is a derivative work — clarify with
authors before any license/release), G1 license, layout, concept, manual, tests.
